What bit rate is required to equal the quality of FM radio?
“Thus = 12 x 30,000 x 2 (2 channels) = 720Kbps (CD is 1411kbps) that is uncompressed.”

Format | Bit rate | Compression ratio | File size per minute | Notes |
WAV | uncompressed | 1:1 | 10 MB | If the wave wav file was sampled at 16 bits/44.1kHz, you've got CD quality sound |
MP3 | 160 kbps | 9:1 | 1.5 MB | Very low compression, superior sound quality |
MP3 | 128 kbps | 11:1 | 1 MB | The standard "CD quality" bit rate |
MP3 | 96 kbps | 15:1 | 700K | Considered "near CD quality" |
MP3 | 64 kbps | 22:1 | 400K | About the same quality as an FM radio station |
